In Part 1 of this Garden Pavilion Build we got the posts up and the side girts installed.
Part 2 – Build the Timber Frame Gazebo
Cut Upper Beams
The next step is to cut the upper beams to length and mark their crown.
The ends have a quarter ellipse cut into them.
I laid out and cut a pattern from plywood according to the drawings. These curves are then traced on the ends of the beams.
I’ll lay out and cut the shallow groove where it sits on the top of the post. I like the beams to sit down on the post an inch. I like this look and you may have seen me do this on other projects. I think it’s worth the extra time and effort.
As with all the grooves or laps on this timber frame gazebo build, I make a series of close parallel cuts using a large speed square with the circular saw set to depth. Then break these off with a hammer or wooden mallet. Then clean up the groove with a chisel.
Now to cut these quarter ellipse end profiles. For this I use a jigsaw with a long blade. I did a full review of this jigsaw. See the video.
I cut these from the end inward. With a handsaw I make a shallow straight, square cut in the end of the beam first. This helps to start the blade squarely and improves the accuracy of the cut.
During this hot and dry summer there were forest fires burning throughout the west. The smoke in the air on a few of these days made it look like sunset all day long. I decided to leave the footage as the camera saw it and to not colour correct it.
So it was kinda fitting that I burnt the wood on these cuts by turning a bit too sharply at the end of the curve. I sanded the char marks off afterward.
I’ll attach the beams to the tops of the posts with a long lag bolt. I countersink the head and washer with a forstner bit, then drill a pilot hole, then finish with a bit slightly smaller than the diameter of the lag bolt shank.
The beams are then chamfered too. You can see the bow in these beams that I oriented up as the crown.
Put Timber Frame Gazebo Beams in Place
I enlisted the help of my neighbor Calvin to set these beams on the top of the posts. And this went well and they fit the first time.
I drill into the post with a long bit and run in the lag bolt with a socket wrench.
